He just done a overhaul to the game, added new game mechanics, animations, power ups, weapons, items and new interfaces etc and really the old content isn't really cut while most of it isn't in v0.40. He just haven't reimplement all of it back in the game yet along with some new content that isn't implemented yet like that dungeon location. The only missing content is the sex scenes, interactions with Jessica, Lisa, Cherry, Roxie, the two police women Ann and Susan, Samantha on TV, the Demon Hunter, Fiddle the demon, Roxie's woman guards, their secret base and quests etc which will be all restored when he finishes restoring the game. He is basically rebuilding the game while adding new content to it.
